FIELD OF THE INVENTION

The invention relates to a backpack accessory, which can be used in mountaineering, tourism, trips, hikes, various trainings, or while gardening. It could also be used in sports such as: running, sports walking, and while carrying school supplies, etc., and more.

BACKGROUND OF THE INVENTION

There is a wide range of backpacks of various structures available in the market place. Some of them are exemplified in the following Russian Federation patents:

In the patent of the Russian Federation No. 2282389, published Aug. 27, 2006, an open multifunctional backpack is shown. This backpack consists of several smaller bags for transportation of cargo with shoulder straps and a thigh belt. The backpack is additionally equipped with a protective case, made in a rectangle, the corners of which are equipped with one-piece zip clasps connected with the backpack via a detachable connection. The detachable connection includes a zip clasp made of waterproof material that forms a pocket with the backpack. The backpack is further divided in at least two sections, both of which have input sections equipped with clasps.

In another Russian Federation patent No. 109646, published Oct. 27, 2011, a backpack containing two internal volume wings with an adjustable belt and shoulder straps is shown. Here, side pockets are attached to the walls on the side surfaces of the backpack and to the rear walls of the pockets. There are also several rows of transverse bands separated by lines with the possibility of attaching to them to the attached pockets.

Chosen as a prototype in the drawings, the patent of the Russian Federation No. 71867, published Mar. 27, 2008, is a backpack with two shoulder straps made of polyethylene attached from the top of the backpack to the bottom. The pocket is of the “t-shirt” type form of a pocket, and the side areas of the pockets are met with flap and seam. On the bottom of the pocket the straps are attached to the bottom with a shift from the middle.

There are several disadvantages with the above-described backpacks. First, the complexity of their designs, with pockets and straps, makes them cumbersome to carry around. Second, to carry backpacks is highly uncomfortable because they are usually designed to increase their volume to carry more payloads and not to be comfortable. Similarly, most advances in backpack technology today are aimed to increase the compactness and to protect against external forces, such as wear and tear, but give no beneficial solutions to improve a user's comfort level when carrying them.

DETAILED DESCRIPTION

A backpack improvement containing strap-holders attached to the shoulder straps of a backpack solved the above posed problems. The strap-holders include a strap attached to the shoulder strap at a one end and a holding-part, embodied in a grip or handle, to be held by a user at the other end.

When wearing the loaded backpack, users often hold on to the front of the shoulder straps. Shoulder straps are not designed for such use, but are there to adjust the user to the backpack's structure. In one of the embodiments of the claimed backpack improvement is a set of strap-holders for the care and training of hands and ensuring the comfort of a user when carrying a backpack. This is accomplished by allowing the user to grip on to handles at the free ends of the strap-holder when carrying his backpack.

FIG. 1 shows the perspective frontal view of backpack 1 that includes body 2, with an internal volume for the carrying of cargo, attached to shoulder straps 3. Here, the front parts of the shoulder straps 3 are attached to a set of strap-holders 4 with holding-part 5 on their free ends. In one embodiment of the invention, the use of a strap-holder could be as follows: (1) put on backpack 1 using shoulder straps 3 and place hands on holding-part 5 on strap-holders 4; (2) pull on the holding-part 5; and (3) train the muscles of the hands through compression and decompression of muscles while carrying the backpack 1.

FIG. 2 shows a perspective frontal view of one embodiment of the backpack improvement that includes strap-holders 4. Here, shoulder straps 3 are attached to a set of removable straps 6 attached to strap-holders 4 at a first end, and to the belt that holds the user's pants 7 at a second end, thus linking the shoulder straps 3 to the belt. Similar to FIG. 1, the front part of the shoulder straps 3 are attached to strap-holders 4 by holding-part 5 attached to their free ends. As an alternative, the elastic removable straps 6 could be attached to the pants 7 directly, at the belt-holders, as shown here in FIG. 2. Attachment to the pants or belt is possible if the ends of the removable straps 6 are fitted with carabiners 8 clamps or something similar. The attachment of carabiners 8 clamps should be made at the front of the shoulder straps 3 to the belt or pants 7. This arrangement allows the hands to tension the strap-holders 4 increasing the convenience of carrying a backpack by creating a more even distribution of weight of the backpack to the musculoskeletal system of the user.

Similarly to FIG. 2, FIG. 3 shows a perspective frontal view of one embodiment of the backpack improvement that includes shoulder straps 3 with a set of removable straps 6 that are cross attached from the shoulder strap 3 at one end to the strap-holders 4 at the other end. Here, strap-holders 4 are demountably attached to shoulder straps 3, on a first end, by carabiner 8 clamp, while attaching to both to removable straps 6 and holding-part 5 on their free second end. Here, removable straps 6 could be attached at one end to a loop placed on strap-holders 4, and at the other to the opposite shoulder strap 3, thus, two removable straps 6 will be placed crosswise in relation to each other. This arrangement provides for a significant increase in user comfort when carrying a backpack. The strap-holders 4 separately or in combination with removable straps 6 form a system to train muscles by allowing both hand and arm movements while increasing a user's comfort when carrying payload.

FIG. 4 shows a detailed perspective frontal view of one embodiment of the strap-holders 4.

The strap-holders 4 contain a strap made of elastic material and a handle or holding-part 5 made of non-elastic material attached at its end. As previously shown in FIG. 1, the strap-holders 4 are attached to shoulder straps 3 by stitching.

FIG. 5 shows a detailed perspective frontal view of one embodiment of the strap-holders 4 with the holding-part 5 at one end, while the other end is attached to shoulder strap 3 through carabiner 8. It is envisioned that the holding part 5 may be a horizontal or vertical bar type handle to provide for the paramount use of the strap-holders 4 for the training of hand and arm muscles.

In another detailed perspective of the backpack improvement, FIG. 6 shows frontal view of one embodiment of strap-holder 4 that includes a short strap sewed to the front of the shoulder strap 3 at a one end with a FASTEX type buckle 9 at the other end. It is envisioned that the short strap sewed is not needed and that a FASTEX type buckle 9 can be placed directly on to the shoulder strap 3 instead of using attachments such as stitching as shown previously in FIG. 1 and FIG. 4, or carabineer buckles on FIG. 5. Strap-holders 4 are attached with a FASTEX type buckle 9 to make the strap-holders 4 removable.

FIG. 7 and FIG. 8 are detailed perspective frontal views of one embodiment of the holding-part 5 in a horizontal handle and a vertical handle respectively. Similarly, FIG. 9 shows a detailed perspective frontal view of one embodiment of the holding-part 5 in an adjustable ring formed by the strap-holder 4 itself. An adjustable strap-holder 4, and the vertical and horizontal handles, provides the opportunity for the user of strap-holder 4 to adjust to their own strength and anatomy.

FIG. 10 shows frontal view of one embodiment of strap-holders 4 with the holding-part 5 in the form of a ball, and FIG. 11 shows a frontal view of one embodiment of strap-holder 4 with holding-part 5 in the form of ring. Holding-part 5 could be made in the shape of a ball, or a ring, and either filled with air, foam or similar matter. This will allow flex-movements to train hand and arm muscles and allowing increasing a user's comfort when carrying payload.

It is envisioned that removable straps could be made of elastic material and the strap-holders equipped with a device to allow for adjustment of length. A typical length of a strap-holder could be from between about 1 to 66 cm.

The invention represents a backpack improvement, which is simple but helps alleviate the movement of the backpack against a user and increases user comfort when carrying a load. The invention also provides the possibility of training a user's hand. As an alternative, a set of detachable straps can be attached to a user's pants or belt, while the hands will provide tension on the strap-holders increasing the convenience of carrying a backpack due to a more even distribution of weight.
